                  x.appendTo('#form .con') // the length is not working here if I use it in the front of the div while declairng the variable.
                });

                $('.Minus').on('click', '#rem .Minus', function () {

我正在尝试添加索引并删除单独添加的行。我尝试使用div的长度，但如果我将它附加到输入框的前面则不会触发。这是plunker http://plnkr.co/edit/4P6HWu9jVTmZhOnEhMdb?p=preview

你走了：

＆＃13;

$('#add').click(function() {
  var x = $('<div class="ui-state-highlight">' + ($('.con div').length + 1) + '<input type="text" class="form-control" ng-model="input.field" placeholder="Name"/><input type="text" class="form-control" ng-model="input.value" placeholder="Email"/><a href="a"><span class="glyphicon glyphicon-move"></span></a><input type="button" class="form-control Minus" value="-" /></div>');
  x.appendTo('#form .con') // the length is not working here if I use it in the front of the div while declairng the variable.



});

$('.con').on('click', '.Minus', function() {
  $(this).parents(".ui-state-highlight").remove();
});

$("span").sortable({
  connectWith: ".con"
}).disableSelection();

您有两个class声明，因此我合并它们以获得form-control Minus类。
还修复了.on()处理程序的选择器。

编辑：您的新行标记由

var x = $('<div class="ui-state-highlight"><input type="text" class="form-control" ng-model="input.field" placeholder="Name"/><input type="text" class="form-control" ng-model="input.value" placeholder="Email"/><a href="a"><span class="glyphicon glyphicon-move"></span></a><input type="button" class="form-control Minus" value="-" />' + ($('.con div').length + 1) + '</div>');

要将索引移到前面，请将此($('.con div').length + 1)移到前面，如下所示：

var x = $('<div class="ui-state-highlight">' + ($('.con div').length + 1) + '<input type="text" class="form-control" ng-model="input.field" placeholder="Name"/><input type="text" class="form-control" ng-model="input.value" placeholder="Email"/><a href="a"><span class="glyphicon glyphicon-move"></span></a><input type="button" class="form-control Minus" value="-" /></div>');

如何在动态添加的可排序输入框中删除div并在添加的输入前面编制索引
